Geomagnetic Activity Chart

NOTE: The Geomagnetic Activity Chart is created using MAGNE KA, one of IUWDS codes. MAGNE KA is generated based on the geomagnetic observation at Kakioka geomagnetic observatory. Moreover this chart functions as the active map linked to the GMS/SEM high energy particle flux database. If you click your mouse on it, you can refer the corrensponding daily plot of the GMS/SEM high energy particle flux.
